The Portuguese worked with Lampard twice as Chelsea manager, during his first spell between 2004 and 2007 and then again when he returned to Stamford Bridge in 2013/14.
But Mourinho also had praise for a number of the other great players he has worked with:
I went to Inter [Milan], I had [Zlatan] Ibrahimovic, I got [Javier] Zanetti I got to Madrid, I had [Cristiano] Ronaldo. I come back to Chelsea and I find other top players.
I have so many, they gave me so much, it’s not fair to say this is the one. It’s impossible to win so many things without the players so I respect all of them.
